PAGlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 449,304, dated March 31, 1891.

Application filed October 23, 1888. Serial No.288,950. (No model.)

To aZZ whom it may concern.-

Be it known that I, SAMUEL K. \VHITE, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Paging-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to paging or numbering machines of that class embracing a series of printing-wheels or type-disks mounted upon a common shaft, which disks are in the operation of themachine automatically turned to present the proper numbers for printing.

The invention embraces improvements in the devices for supporting and for giving bodily movement to the disks; in a novel repeating mechanism, or means by which the same number may be printed successively two or more times, if desired; in means for inking the type-disks, and in other details of construction in such machines; and it consists in the matters hereinafter described, and pointed out in the appended claims.

In the accompanying drawings, illustrating my invention, Figure 1 is a central vertical section of a machine embodying the same. Fig. 2 is a front elevation of the lower part of the machine, or that portion below the typedisks. Fig. 5 is an enlarged detail side elevation of the parts adjacent to the type-disks as viewed from the side of the machineopposite to that seen in Fig. 1. Fig. 4. is a front elevation of the parts shown in Fig. 3. Fig. 5 is a detail elevation showing the inking de vices only and illustratingthe same in changed positions by dotted lines.'

Fig. 11 is a detail section taken upon line 11 11 of Fig. 1, showing the power-drivin g devices. Fig. 12 is a detail plan section of the overhanging frame-arm, taken upon line 12 12 of Fig. 1. Fig. 13 is an enlarged detail section through the type-disks, taken upon line 13 13 of Fig. 1. Fig. 14: is a cross-section through the type-disks support, taken between two of the disks on line 14. 1 of Fig. 13. Fig. 15 is a detail view illustrating the notched disks of the repeating mechanism removed from the machine. Fig. 1G is a detail side view showing a modified form of the parts of the repeating mechanism adjacent to the notched disks. Fig. 17 is a plan view of the parts shown in Fig. 16.

As shown in the said drawings, A is the main part of the machine-frame, consisting of a hollow or tubular standard, which rests upon the floor at its base and is provided at its upper end with an overhanging arm or goose-neck A, at the end of which the type wheels or disks and devices by which they are immediately actuated are located.

The machine is adapted for actuation both by a foot-lever and by power, and the devices for transmitting motion from said foot-lever and from a counter-shaft located upon the standard A at the lower part thereof to the printing-disks are located within the said tubular frame-standard, so that said devices are concealed from view, and the machine presents to the eye a simple and compact appearance.

Bis the work-table, which is supported by means of a sliding bracket B, sustained upon a vertical bracket B which is attached at its lower end to the frame-standard A. The said bracket 13 is provided at its upper end with a stationary piece or plate B which is arranged beneath the type-disks and sustains the sheet to be printed while the impression is being made.

The work-table B is intended for supporting a book or other bulky article, and is movable vertically, while the surface B which takes the pressure in printing, is stationary, this arrangement of the parts being old and common in similar machines.

C is a typedisk-carrying arm, which is supported upon a pivot C on the frame, and is provided at its free end with a curved plate C which is held and guided between curved guides a a at the end of the arm A of the frame.

The numbering disks or wheels D D are mounted upon a stud Figs. 4, 6, and 13,

appear in the drawings, (except partially in Figs. 13 and 14,) and inasmuch as such devices are common and well kndwn they are not made the subject of special illustration and description herein.

The type-disks are immediately supported by means of a sleeve D, adapted to fit over the stud C by which the wheels are supported upon the arm 0 of the sliding plateO the said sleeve being provided with collars c and c" at its ends, forming shoulders by which the several disks are held upon the sleeve, so that the sleeve, with the several disks thereon, may be removed from the machine without disturbing the relative position of the disks.

As herein shown and preferably constructed, the collar 0 is formed by a ring of greater external diameter than the sleeve, and is se-.

cured to the end of the latter by screws, as shown, Fig. 13, while the collar 0 surrounds the'sleeve and is held thereon by a radial set- The said sleeve and all screw or otherwise. the disks thereon may be turned upon the stud for bringing the types which are in position for printing forwardly or upwardly toward the operator, to enable the same to be cleaned or inspected when desired. For convenience in thus turning the sleeve the latter is herein shown as provided with a milled flange 0 upon the collar 0. The said sleeve D is conveniently held upon the stud (J by means of a thumb-screw D inserted in the end of the stud and provided with a flange or shoulder adapted to bear against the end of the said sleeve, as clearly shown in the drawing's, Fig. 13. V

A vertical reciprocatory movement is given to the arm 0, plate 0*, and parts connected therewith for the purpose of carrying the type-disks toward and from the table by devices constructed as follows: E is a rocking lever, which is mounted upon the pivot-pin 0 and is located within the frame-standard at the side of the carrying-arm C. The said,

lever E is curved or bent to correspond with the shape of the arm A of the standard, and.

the free end of the lever is engaged with the upper part of the plate C The said plate 0 and the guides a therefor are, as before described, conformed to a circular curve concentric with the pivot O of the arm 0. When said lever E is moved or oscillated about its pivot, therefore, it will, by its engagement with the plate 0 give an oscillatory movement to said plate and the arm 0. Said plate 0 is provided with a longitudinal groove or recess in its rear or inner surface, the end of the rocking lever E being inserted in the-upper part of said groove orlrecess. Within the longitudinal groove or recess of said plate 0 between a transverse part of the said plate at the bottom of the groove and the under surface of the said arm, is placed a spirallycoiled spring E. Said spring E, being thus located, obviously serves to transmit the downward pressure of the arm E to the plate 0 when the arm is moved downwardly. Said spring is made of suflicient stiifness to give suitable pressure for printing u nder ordinary circumstances, but is adapted to yield, and thereby allow the stoppage of the downward movement of the type-disks in case said typedisks strike any obstruction affording such resistance as would tend to break or injure said type-disks or the parts supporting them. Such spring furthermore serves to compensate for differences in the thickness of the pile of sheets or book-leaves beneath the disks, it being entirely obvious that the said spring will allow the type-disks to yield upwardly when necessary to prevent a too forcible pressure upon the printing-surface, such as is liable to occur when a relatively-thick pile of sheets or leaves is upon the table. In other words, said spring is adapted to yield upon the occurrence of any excess of pressure above that necessary for printing, so that the machine is adapted to operate upon piles of pa' per, sheets, or cards of varying thickness. This is a matter of great convenience for the reason that to facilitate the handling of the sheets to be numbered a pile of the same is commonly placed upon the table of the machine and the sheets then withdrawn one by one as printed. I

Devices are herein provided for automatically turning the first or end disk of the series of type-disks, which contains the types indicating units, one step at each reciprocation of the disks, such devices operating by thebodily motion of the disks (or plate carrying the same) with reference to the frame. Such devices are constructed as follows: (1' d are ratchet-teeth upon the outside face of the type-disk, which is at the right-hand side of the several type-disks, and which contains the types by which the numerals expressing units are printed. Rotative motion is given to the first disk only by the actuating devices, the other disks being turned in their .orderby automatic devices located between the disks and operating to turn each disk one-tenth of a rotation at the completion of each rotation of the adjacent disk to the right of it, as hereinbefore mentioned. F, Fig. 6, is anoscillating arm mounted upon a collar 0 of the .Stud 0 between the arm 0 and the end of the sleeve D, and F is a spring-pawl pivoted to the said arm F and engaging the ratchet-teeth. To the arm F is rigidly affixed a second arm F Said arm F is arranged in "an approximately-horizontal position, and its IIO outer or free end is pivotally connected with a connecting-bar I, the upper end of which is pivoted to the side of the frame-arm A. \Vhen the plate C and type-disks thereon are reciprocated vertically by the action of the lever E, the arm F will obviously be caused to swing about its pivotal axis by reason of the connection of the outer end of the arm E with the frame, so that at each downward movement of the disks the pawl will be carried backwardly over one of the ratchetteeth cl, and in the upward movement of the said disks the disk D, upon which the ratchetteeth are formed, will be turned one-tenth of a rotation.

For the purpose of holding the several type-disks from movement during the time the said disks are being moved downward and the impression is being made, the sleeve D is provided with a series of longitudinal grooves equal in number to the types upon each disk, said grooves being engaged by spring-pawls d (1 Figs. 13 and lat, upon the several disks. The said spring-pawls are arranged to engage the grooves with sufiicient force to prevent accidental turning of the disks, and at the same time to easily yield and pass out of the grooves when the disks are turned in the operation of the machine. Similarly-acting spring-pawls have, however, been heretofore used for the same purpose, and this feature of construction forms no part of the present invention.

It is obviously necessary that the sleeve D should be held from turning upon the stud (l as the disks are turned in the usual operation of the machine, and to hold said sleeve immovable upon the shaft, while atthe same time enabling it to be released and turned upon said stud at desired times for purposes hereinbefore stated, a locking device is provided upon the arm (1* or other adjacent stationary part, said locking device being adapted to detachably engage the said sleeve. A simple and convenient form of such locking device is illustrated in the drawings, Fig. 13, the same consistingof a sliding pin 0', which is inserted in a guide-aperture in the arm C passes through the collar 0 and engages a hole or recess a in the adjacent end of the sleeve. The said pin is provided at its outer end with a knob or handle 0", by which it may be moved, and with a shoulder or collar 0 near its inner end, which collar is located within an enlargement or recess 3 formed in the said arm C and opening at the inner face of the arm. Cithin the said recess 0 between the bottom or outer end thereof and the said collar c, is placed a spiral spring 0 which tends to hold the pin engaged with the sleeve. The handle c is provided with an annular flange c, which rests against the outer l'aceof thearm 0-, and is provided with an eccentric stud or pin c adapted to enter a recess o in the arm 0', and thereby allow the end of the pin to engagewith the sleeve in one position of the said handle c. When the pin is pulled out and the handle is turned partially around, however, said stud 0 will rest against the surface of the arm O", and thereby prevent the engagement of the pin with the recess of the sleeve, at which time the sleeve may be freely turned for cleaning the typedisks or other purposes, as hereinbefore set forth.

Devices for operating the rocking-lever E, both by the foot of. the operator and by steam or other power acting through a rotating shaft, are provided as follows: Upward movement of the free end of said lever E, by which the type-disks are carried upwardly or away from the work-table, is produced by a spring acting upon the said lever. In the particular construction illlustrated said lever is provided adjacent to its pivot c with a rigid horizontally extendin garm Eiwhich projects through a slot in the rear part of the frame-standard A, and is connected with the upper end of a coiled spring G, the lower end of which is attached to a rearwaidly-extending lug G, cast upon or otherwise secured to the said framestandard. Said lever E is provided with a downwardly-extending rigid arm E located within the hollow frame-standard, which arm E is engaged at its lower end with the upper end of a lever H, mounted upon a pivot 71 which passes through the lever ata point between its ends. Said lever is arranged in an approximately vertical position within the frame-standard, and has its upper end engaged with the front surface of the leverarm The lower end of the lever H engages the upper end of an arm I, attached to a foot-lever I, which is mounted upon a pivott'near the base of the machine, said foot-lever I extending outwardly through a slot in the frame-standard to a position convenient for the foot of the operator standing at the table B.

Devices are provided for actuating the machine by power, such devices being adapted to operate independently of the foot-lever l, and being shown in Figs. 1 and 11. As illustrated in said figures, H. is a short shaft, which is mounted horizontally in a bracket A upon the frame-standard at the rear of the same and adjacent to the pivot h of the lever H. Said shaft H is provided with a cone pulley HZ-and also with a crank-disk ll provided with a crank-pin h, which is arranged in the same vertical plane with or opposite the lever H.

H" is a horizontally-arrangcd arm, which is pivoted upon the pivot-pin 7i, and is provided with a horizontal slot h which is engaged by the crank-pin As herein illustrated, the lever His provided with a central recess or slot adjacent to the pivot 7L, within which slot the end of the arm ll is inserted, as clearly shown in Fig. 11.

From the construction described it is entirely obvious that when the shaft H is revolved vertically oscillatory movement will be given to the arm H" through the medium of the crank-pin h and slot 7L described.

IIO

-Upon the said lever H, beneath the oscilin contact with the under surface of the oscillating arm H ,-said set-screw serving as an adjustable stop or bearing-surface, which maybe moved in adjusting the parts for operation and to compensate for wear. The spring G, acting on the actuating-lever E above described, obviously operates to hold Y the free end of the said arm E and the typedisks elevated and to retain the downwardly-projecting arm E of said arm E at the forward limit of its movement, thereby retaining the lever H 'in position with the end of the arm H in contact with the oscillating arm E. It follows, therefore, that as the shaft H is revolved the arm H will be pressed downwardly in opposition to the spring G at each downward movement of the oscillating arm H thereby moving said lever H and the actuating-arm E in the same manner that it is moved by the use of the foot-lever I. The said arm H however, being unattached to the oscillating arm H the parts may be actuated by the foot-lever without requiring the disconnection of any of the parts to enable the same to operate independently of the slot-and-pin connection with the drive-shaft, it only being necessary that the shaft should be stopped with the crank-pin at the upward limit of its movement, so as to leave the oscillating arm above and free from the arm H when it is desired to move the lever H and other parts by the foot-lever. The stoppage of the crank-pin at the point indicated may be accomplished by the use of any one of a great variety of forms of clutch devices well known to mechanics. The clutch device employed in the present machine for stopping and starting the same is located between the belt-pulley H. and the crank-disk H and is indicated as a whole by'H said clutch device being actuated by means of a foot-lever H connected with the clutch bya rod H Said clutch device forms no part of the present invention, and is not therefore specifically shown and de scribed herein. A spring I is applied to the foot-lever I to hold the same'elevated and to thereby retain the arm 1' thereof free from the lever H when the latter is moved by power in the manner described.

It is often necessary in the use of a numbering-machine of the character herein described that the number printed should be repeated two or more times, and devices have heretofore been made adapted to prevent r0 tation of the units-disk during two or more consecutive movements of the type=disks toward the paper. My present invention embraces an improved device or attachment for this purpose, which is made as follows: I J J Figs. 1, 3, 4, 6, 7, and 8,arenotched disks, which are mounted upon a common shaft j, the ends of which are supported in brackets j j, aflixed to the front surface of the plate 0 near the upper end thereof and projecting forwardly from said plate. Said disks age splined to the shaft 3' and turn with the latter, and upon said shaft is placed a rigidlyattached ratchet-wheel J pawl mounted upon one of the guides at of the frame-arm A at the upper end of said guide and constructed to engage the said ratchetwheel J Said pawl J is so disposed as to turn the said ratchet-wheel a distance of one tooth at each reciprocation of the wheel. The said ratchet-wheel is provided with an even number of teeth, and a number which is divisible by 2, 3, and 4, the particular wheel shown having twelve teeth. One of the disks, as J, is provided with six equidistantnotches, another, as J, with four notches, and another, as J with three notches, said notches operating in a manner and for a purpose hereinafter set forth. Lisa v'ertically arranged lever pivoted upon a horizontally-arranged stud l, which is attached to the side of the plate 0 so as to sustain the said lever L in position outside of andadjacent to the end of the framearm A, Figs. 4 and 6. The lower end of the said lever L is provided with a cam-plate L, located near theratchet-teeth d d of the typedisk D and near the path of the spring-pawl F, which engages said ratchet-teeth and turns the end disk of the series, said cam-plate being curved upon its working-face in a circular curve concentric, or nearly so, with the typedisks. The spring-pawl F is provided with a rigidarm F extending rearwardly from its pivot and provided preferably with an antifriction roller f at its end. The said camplate L may be moved toward and from the central axis of the type-disk by swinging the lever L supporting it upon its pivot, and said cam-plate L is so disposed with relation to the arm F of thepawl F as to engage said arm and press the latter inwardly to hold the free end of the pawl out of engagement with the ratchet-teeth when saidcam-plate is in its position nearest the central axis of the disks. It follows from this construction that when the lever L is moved so as to bring the camplate nearer the central axis of the disks the pawl F will be held free from the ratchet-teeth, and when said lever is moved to carry the cam-plate outwardly or away from the axis of the disks the pawl will be allowed to engage said teeth, it being of course understood that the said cam-plate is arranged to extend through or over an arc corresponding with the arc through which the roller f uponthe end of the arm F of the pawl moves as said pawl is bodily oscillated. By thrusting the cam-plate toward the center of rotation of the disks, therefore, the pawl will cease to act upon the ratchet-teeth, and the disks will remain stationary or will J is a springnot be turned. hen the said cam-plate is swung away from the central axis of the disks, on the contrary, the end disk of the series will be turned one-tenth of a rotation at each bodily reciprocation of the disks in the manner before described. The lever L is moved or swung so as to carry the cam-plate L toward and from the axis of the type-disks by means of a movable bearing-finger adapted to act upon one of the notched disks J J J and connected with the upper ends of the said lever L so that said lever will be moved as said finger is carried inwardly and outwardly in the turning of the notched disks, said finger being carried toward the disks either by spring-pressure or by gravity,

according to the arrangement employed. In a particularconstruction (illustrated in Figs. 1 to 14 of the drawings) the upper end of the lever L is bent at right angles to the main part thereof, so as to form a transverse bar Z, Fig. 8, extending past the said disks J J J parallel with the axis thereof. K is a finger arranged to slide upon the bar Z, and adapted to engage at its free end with the periphery of one of the disks J J J Said linger K is provided with a clamp-screw 7c or other clamping device by which the finger may be clamped immovably upon the said bar Z. Said finger may be shifted upon the bar Z into position opposite either one of the disks J J J*, as desired. L is a spring attached to the lever L and acting against an opposing part upon the plate C (in the instance illustrated the arm 0 said spring acting to throw the upper end of said lever L and the transverse bar Z toward the notched disks. The finger K is thus thrown and held in contact with the disk which is opposite it, so that as the disks are rotated the finger will move inwardly or outwardly or toward and from the shaft supporting the disks, thereby transmitting a corresponding movement to the lower end of the said lever L, by which the cam-plate L is held adjacent the axis of the type-disks when the finger rests upon the outer periphery of the notched disk, and is held remote from the said axis when the finger sinks into one of the notches of said notched disk. It follows that when the finger K is acting upon the outer periphery of one of the notched disks the cam-plate L will be held in position to prevent the pawl I from working, and when the said finger drops into one of the notches of the disk the cam-plate will be thrown outwardly to allow the pawl to engage the ratchet-teeth upon the type-disk.

The machine shown in the drawings is adapted to repeat the same number in printing either two, three, or four times, depending upon the disk J, J, or J with which the finger K is engaged. The notches of the said disks J J J correspond in angular position with the ratchet-teeth of the ratchet-wheel J so that one of said notches will stop at a point beneath the finger K during the termination of one of the partial turns given to said ratchet-wheel by the action of the pawl upon the frame. It follows, therefore, that if the said finger K is engaged with the disk J, having four notches, said finger will drop into one of said notches at each third reciprocation of the printing-disks, and the machine will repeat the same number three times. Similarly when the finger is engaged with the disk J having three notches, it will repeat four times, and when engaged with the disk J, having six notches, it will repeat twice before the numher is changed by the shifting of the disks. By providing a machine, therefore, with a plnrality of notched disks, and with a sliding finger adapted to engage either of said disks, and by making the ratchet-teeth a multiple of the number of notches in the disks, the machine may be made to repeat the number printed any number of times desired.

The notched disks J J J in addition to the deep or main notches therein, which allow the finger K to move toward the center of the disks for causing the machine to repeat, in the manner described, are also provided with intermediate relatively shallow or small notches j f, Fig. 15, which notches correspond in angular position with the teeth of the ratchet-wheel J, so that at each partial rotation of the disks given by the action of the pawl J upon said ratchet-wheel the finger K will engage either one of the large notches or one of the shallow intermediate notches j j above described. Engagement of the finger K with said notches 3' serves to hold the several disks from turning either backwardly or forwardly after the same have been moved by the pawl J 4 and ratchet-wheel. In view of the advantages in point of simplicity of construction and operation obtained by the use of said shallow notches j in the disks a construction embodying the same is herein claimed as part of my invention.

InFigs. 16 and 17 are shown a somewhat different construction in devices for actuating the leverL from a series of notched disks arranged in the manner above described. In this instance K is a swinging arm pivoted by means of a pivot-pin 71$ to a standard 713 at the upper end of the plate 0 Said arm K is arranged horizontally and extends forwardly with its free end over the disks J J J At said free end of the arm a transverse bar K is seen red to the same, said bar extending over said disks J J J parallel with the shaft thereof, and upon said bar is mounted a sliding finger K arranged to engage the periphery of one of the said notched disks in the same way as the finger K, hereinbefore described. The finger K is provided with a clamp-screw, by which it may be secured opposite either of the disks, as desired. In this construction the free end of the arm K and finger K thereon are free to move vertically, and the weight of the parts keeps the said finger in contact with the disk engaged by it, with the aid of a spring, if nec- IIO essary. Theupper end of the lever L in this construction extends to a point opposite the slide-bar K and upon said slide-bar is placed apin which engages an inclined or cam slot- 1 in the upper end of said lever L. Said cam-slot Z is inclined in such manner that the said lever will be swung or moved as the disks revolve in the same manner as the said-lever is moved by the devices hereinbefore described. F Fig. 6, indicates a short arm or finger-piece, which is attached to the end of the arm F of the pawl F, and is so arranged that the finger of the operator may be easily placed thereon for holding the pawl out of engagement with the ratchet-teeth d, to free the end disk D from the pawl, when it is desired to turn the disk-supporting sleeve D and disks thereon, as hereinbefore described.

In connection with a machine embracing the features above set forth, any suitable inking device for applying ink to the types prior to the making of each impression may be employed. A novel form of inking device embracing an oscillating inking-roller and inkdistributing disk, which is bodily moved to bring it into position for contact with the inking-roller, and which is provided with an improved means of supplying the same with ink, is herein shown, and is constructed as follows: M is an inking-roller, which is mounted upon the end of'an arm M, which arm is pivoted by means of a pivot-pin m to the side of the frame-arm A opposite to that at which the disk-turning devices above described are located. Upon the said arm M, adjacent to the pivot m, are two short prongs m m which are located in position to be engaged by a horizontally-arranged pin m, secured to the reciprocating plate 0 which carries the disks. When the disks are at the upward limit of their movement the pin m engages both of said prongs and holds the inking-roller at a point slightly forward of the row of types which are in position for'printing. As the disks descend, the said pin m presses downwardly upon the prong m thereby swinging the roller -M backwardly past the row of types, which roller as soon as the pin leaves said prong m is carried still farther backward by the action of a spring M which is attached to said arm 1V and to an adjacent part of the machine. As the type-disks rise, the pin m, when said disks are near the upward limit of their movement, passes the lower prong m and strikes the prong m (which will be commonly somewhat longer than the lower prong,) swings forward the said arm M, and thereby carries the inking-roller forward beneath the type-disks. N is the inking-disk, which is located at the rear of the type-disks in position for contact therewith of the inking-roller when said roller isthrown backwardly or away from the type-disks by the device above de scribed. Said inking-disk is mounted upon the end of ashaft N, which is rigidly attached to a block or hub N, which has bearing upon forty-five degrees.

the lower end of a swinging arm 0, pivoted p at 0 to the frame-arm A. The pivotal connection between the hub N and the arm 0 is hereinshown as fprmed by a stud n, Fig. 9, upon the hub,which stud passes through a bearing-aperture in the lower end of said arm 0, a collar n being placed upon the end of the stud to hold the same in engagement with the arm. The connection of the disksupporting arm N with the arm 0, in the manner described, allows the said disk to swing in a vertical plane, while the pivotal connection of the arm 0 with the frame permits a bodily movement of said disk toward and from the type-disks. The hub N is provided with two rigid arms N N arranged nearly at right angles with each other, the arm N extending upwardly and the arm N extending rearwardly therefrom when the disk is in its normal position. 0 is a link connecting the free end of the arm N with the frame-arm A, said link being pivoted to the frame-arm at a point considerably at the rear of the arm 0, so that the link stands at a downward and forward inclination of about 0 is anotherlink connecting the upper end of the arm N with the actu: ating-arm E, by which motion is given to the type-disks. Said arm 0 is also inclined downwardly and forwardly from its point of connection with the arm E, so that when said arm E is depressed, the arm N is thrown forwardly, thereby turning the hub N in a direction to swing the disk N downwardly. The link 0 serves to hold the arm 0 from movement, except when the arm N and disk are moved in the manner described, when said link 0' causesa backward movement of the arm 0 and a bodily rearward movement of the inking-disk, in the manner clearly illustrated by the dotted lines in Fig. 5 of the drawings. The inking-roller M is so disposed with relation to the face of the disk N that it will come in contact with the lower part of said disk shortly after the type-disks begin their downward movement, the parts being shown in full lines in Fig. 5 in position oc-' cupied by them at the moment theinkingroller is brought in contact with the inkingdisk. After the inkingroller is brought against the disk the further downward movement of the actuating-arm E swings or carries the inking-disk downwardly and rearwardly, so that the inking-roller will move or roll over the face of said inking-disk, the roller being held against the disk in this movement of the same by the action of the spring M The position of theparts after the actuating-arm E has completed its downward movement is illustrated in dotted lines in said Fig. 5. This bodily movement of the inkingdisk, combined with its swinging movement about the pivot n, causes the face of the disk to move backwardly in a nearly straight line, so that the inking-roller M remains practically immovable during such movement of the inking-disk. The spring M allows such slight movement or yielding of the inkingroller as is rendered necessary by the slight curvature of or irregularity in the path of the inking-disk, due to the compound movement producedby arrangement of the parts supporting it.

In inking devices as heretofore made, wherein the bodily motion of the inkingroller is prolonged in order that the same may pass over the inking-disk, the extent of such bodily movement is so great as to require a very rapid motion of the roller, thereby not only tending to rapid wearing out of theparts, but rendering liable the soiling of the paper being printed or neighboring articles by the casting off of particles of ink from the surface of the roller when the latter is suddenly stopped at the termination of its outward movement. In the construction described not only is the inking-disk brought close to the type-disks, but the inking-disk itself is moved to cause the rol er to come in contact with all parts of the disk, so that such movement of the disk lessens the bodily movement of the roller necessary for suitably inking the type.

The machine shown in the accompanying drawings is provided with a novel and con-' venient ink-supply device or fountain for supplying ink to the surface of the inkingdisk N. Such ink-supply device is shown in Figs. 9 and 10, and is made as follows: P is an ink-fountain, herein shown as consisting of a stationary piston P and a movable 1101- low cylinder P having a central screw-stem p, which engages a screw-threaded aperture at the center of the piston, said cylinder being adapted to contain ink, which is forced through passages 17 p in the piston by turning the cylinder so as to move the threaded stem through the piston and thereby advance the piston into the cylinder. These devices for holding and expelling the ink are substantially similar to those heretofore used in a well-known form of lubricating device and are not in themselves essential to the operation of the invention, inasmuch as other forms of ink-supplying receptacles 0r fountains-as, for instance, a fountain acting by power or by gravitymay be substituted for the particular one herein shown with substantially the same result, P is a pipe or tube attached to the piston P and communieating with the exit-passages p, which lead from the interior of the cylinder. The arm N, which sustains the .disk N, is hollow and is adapted to receive the tube P which tube is made of such length that when inserted in the said arm its end is flush with the surface of the said disk. In the particular construction of the parts illustrated the ink-supply tube P is inserted in a projection 13 of the piston P at right angles to the latter, and the hub N to which the arm N is attached, is recessed or slotted to receive the said part 19 of the piston, so that when the said tube P is inserted into the said arm N the part 23 will extend outwardly through the slot or recess n of the hub, and the fountain will thereby be sustained with its axis at. right angles to the said arm N. The fountain P is desirably located in this manner in order that it may stand in position convenient to be grasped and turned by the operator for feeding ink to the disk, it being entirely obvious that if the tube P were arranged inv line with the axis of the cylinder P the fountain would stand at the rear of the hub N and in a position exceedingly inconvenient for the operator. The slot or recess a of the hub N is desirably made sufficiently deep to allow the part 1.7 of the fountain to pass into the notch in the said hub, and a locking device is provided for securing the fountain in place, (herein shown as formed byawedge or key 11 which is inserted through a vertical slot in the hub behind the said part p of the fountain, in the manner clearly shown in the drawings, Fig. 9.

The ink-supply tube may communicate at its outer or exit end with a passage leading through the center of the disk to the outer face thereof, in which case the said tube will terminate short of the said outer face of the disk. I prefer, however, to provide the disk with a central hole of sufficient size to receive the end of the tube P and to bring the said end of the tube flush with the surface of the disk. This construction I employ to enable ink of one color to be easily substituted for ink of another color by removing one fountain and substituting another fountain con taining another kind of ink. hen the inksupply tube P extends to the face of the inking-disk, it is only necessary in changing the color to wipe off the face of the disk and then remove the ink-fountain and tube, when the inking-disk and connected parts will be left entirely clean and a new fountain containing ink of another color may be substituted without liability of any admixture of the colors. In case the ink-supply tube did not extend to the face of the disk a hole or passage in the disk, forming a continuation of the supply-tube, would be necessary for the passage of the ink, and it would be very difficult to entirely remove the ink from said disk and passage in changing from ink of one toink of another color. Asherein illustrated, the tube P is provided with a reduced cylindric end 19 which its in a small opening at the center of the said disk. The said inking-disk is adapted to turn or rotate freely upon the said shaft N, and, as herein shown, it is held upon the arm l by means of a spring-arm 11 which is attached to the hub N and the free end of which is bent at right angles to the arm N and engages a circumferential groove n formed in a hub n" upon the said disk N. Suitable devices may be applied for turning the said disk N automatically through a portion of a rotation at each bodily reciprocation of the disk; but such turning devices are not necessary, inasmuch as the disk may be rotated byhand at suitable intervals to cause the ink to be properly distributed thereon. In Fig. 3 of the drawings the said disk is shown as provided with a milled edge, by which it may be easily turned by the fingers of the operator.

Devices for supporting the work-table B and for moving the same vertically for purposes of adjustment in working upon books or piles of paper of different thickness are herein provided as follows: The bracket B, which immediately supports the table B, has sliding engagement with a vertical guide b of the bracket B which, as before described, is

cast upon the front face of the standard A.

Q is a screw-shaft, which is mounted at'its lower end in a bearing 1'), cast upon the bracket B at the lower end of the latter and engaged at its upper end with an interiorlyscrew-threaded lug or projection B upon the sliding bracket'B. Said screw-shaft is provided at its lower end above the bearing 12 with a beveled gear-pinion g. Q is an obliquely-arranged shaft mounted at its lower end in a bearing 11 located at the lower end of the bracket 13 adjacent to the bearing 1) and having bearing at its upper end in a bracket B bolted to the bracket B in the manner illustrated. Said shaft Q is provided near its lower end with a beveled gear-pinion q, intermeshing with the beveled gear-pinion q of the shaft Q, and is provided at its upper end with a hand-crank Q by which said shaft Q may be turned for giving rotary movement to the screw-shaft Q. Said shaft Q is disposed in an inclined position, in the manner illustrated, so as to bring the crank Q at one side of and below the work-table and in position convenient for the operator. When the shaft Q is rotated by turning the crank Q, the table will be raised and lowered by the sliding of the bracket B upon the guides 11. R is a traveling band or ribbon adapted to pass beneath that part of the surface of the table which comes opposite the type-disks, said traveling band being employed in paging books and doing similar work where the numbers are printed on both sides of the paper, and the sheets are inserted singly or one by one beneath the type-disks in printing, it being entirely obvious that ink from the printed numbers on one side of the sheets may be struck off or transferred to the supportingsurface below it when the pressure isbrought upon the opposite side of the sheet in making an impression thereon, sothat the, traveling band constantly presents a new surface beneath the paper, and thereby avoids anyaccumulation of the transferredink at one point and the soiling or defacement of the work thereby.

band has heretofore been used, the only features of novelty in connection with said band i herein illustrated being embraced in the devices shown for giving movement to the same. The table -B is recessed or:slotted to receive A similarly-located traveling the upper end of the standard B, which latter supports the plate B which receives the pressure of the type-disks, and also supports the guide-rollers r r, by which the band is sustained in suchmanner that it may pass over said plate B r indicates a third guide roller for supporting the lower or under part of the band free from the adjacent parts of the bracket B and r is another guide-roller for the lower portion of the band, which roller r is mounted upon a suppo1'ting-arm-R ,attached to the bracket B Attached to the said roller 1 is a ratchet-wheel 1*. R is a rocking lever mounted concentrically with the said roller r and ,.,ratchet-wheel r and carrying a spring-pawl r which engages the teeth of said ratchet-wheel. R is a connectswinging arm R and at its opposite end to the lever H, hereinbefore described. Said link R serves to transmit the oscillatory movement of the said lever H to the swinging arm R and to thereby move said arm so as to carry the pawl r over the ratchet-wheel W, and thus turn the same continually during the operation of the machine. Said ratchetwheel being rigidly attached to the roller 7 the same is turned with the ratchet-wheel, and the band B thereby moved or shifted forward a short distance each time the typedisks are actuated and an impression is made. An important advantage is gained in a machine arranged, as shown, with a typedisk mounted upon a stud, which is supported by a single arm 0 located at one side of the type-disks, by arranging the devices by which the type-disks are turned at that side of the disks nearest the said supporting-arm O, for the reason that this construction enables the several disks to be removed from. the supporting-stud without disturbing or requiring the removal of the disk-turning devices.
